T0 all fije/mm it may concern Be it knownthat I, ANDREW T. PETERSEN, acitizen of the United States, residing at Colorado Springs, in thecounty of El Paso and State of Colorado, have invented new and usefulImprovements in Glide-Casters, of which the following is aspecification.`

The invention relates to furniture casters, and more particularly to theclass of glide casters for use in furniture.

The primary object of the invention is the provision of a ycasterwherein the tread thereof is constructed to prevent the scratching ofthe flooring or foundation when supporting an article of furniture, andwhich will enable the latter to glide thereover so that the article offurniture can be conveniently moved from one point to anotherirrespective of the unevenness in the flooring or foundation, and alsowhich will obviate the wrinkling of a floor covering should the articleof furniture be moved thereon.

Another object of the invention is the provision of a caster which canbe readily fastened in an article-of furniture so as to prevent thedropping of the castor therefrom when the article of furniture islifted,

yet the castor proper can be readily detached from the article offurniture without necessitating the removal of its holder there- Afurther object of the invention is the provision of a caster Which willreadily glide over a floor or foundation whether having a polished orroughened surface, and which Will obviate the marring'or scratching ofthe iioor or foundation when the article of, furniture supported by thecasters is being moved, the castersbeing of novel `construction topermit the automatic adjustment thereof in event of unevenness in theflooring or foundation, and the ready mounting thereof in position 1n anarticle of furniture or removed therefrom, the holder for the4 V casterbeing constructed to permit the convenient fastening of the same in the`article of furniture so as to avoid the possibility of the dropping ofthe caster or its holder Whenthe'article of furniture is lifted. Y

` A still further object of the invention is the provision of a casterof this character i A which is extremely simple in construction,

reliable and eilicient in operation, strong,

durable, and inexpensive inmanufacturel With these and other objects inview, the

Specification olf Letters Patent. Patented Sept, 28, Application filedJune 3, 1914. Serial No. 842,213.

invention consists in the const'ructiom combination and arrangement ofparts as will be hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereunto appended.

In the drawings :t-Figure 1 is a fragmentary vertical sectional Viewlthrough the support of an article of furniture, showing the casterconstructed in accordance with the .in vention mounted therein. Fig. 2is a vertical sectional view through the caster.` Fig. 3 is aperspective view of the holder, Fig, 4 is a sectional View on the line 1-lof Fig. 2. Fig. 5 is a View similar to Fig. l, showing a modified formof caster. Fig. 6 is a vertical sectional view thereof. Fig. 7 is aperspecview on the line 8-8 of Fig. 6.

Similar reference characters-indicate cor-v respondingparts throughoutthe several views in the drawings.

Referring to the drawings in detail, A designatesa portion of thesupport for an article of furniture, for example, the leg thereof, inwhich is fitted the caster hereinafter fully described.

The caster comprises a glide knob 10 formed in its tread face With asocket 11 in which is fitted a tread body 12 preferably vmade fromleather, although the same may be made from any other flexibleI orresilient inturned circular yflange 17 provided with diametricallyopposed notches 18, the shank or stem 13 beingv of greater length thanthe sleeve 14 and formed at itsffree end with dialnetrically opposednibs 0r lugs 19 which are of a size corresponding to the notches 18 soas to pass therethrough for detachably .locking the shank or stem 13 inthe sleeve 14, and in this manner the caster is fastened in the holder.Integral with the upper end of the sleeve 14 is a split resilient bonnetItive view of the holder. F ig.` 8 is a ySectional 20 forming aplurality of spaced dovvn-i adapted for insertion in the socket C With'inthe support A so that the arms 21 will frictionally engage the Wall ofthe socket C for the firm fastening oi the holder in the support, thering B being designed to abut the support A to limit the insertion ofthe holder therein and prevent its Working in- Wardlysunderthe weight ofthe article of furniture, I.

ln Figs., 6 to 8 of the drawings there is shown a modified form ofcaster which comprises a substantially seinispherical shaped glide cup23 in which is iitted a tread piece 24, the same being formed preferablyfrom leather, yet it may be made from any other suitable flexible orresilient material or composition of materials and is heldfiiast in thecup 23 in lany suitable manner. Rising centrally from the cup is a stemor shank which. is detachably engaged vfor rotation` in a holderhereinafter fully described.

The holder comprises a sleeve 26 for re-v ceiving the stem or shank 25and is formed with an annular flange 2'?" at one end to engage anannular shoulder 28 formed on the stem' or shank 25 concentrically aboutthe same, the opposite end of the sleeve 26 being formed with aninturned circular-flange 29 provided with diametrically opposed notches30? through which pass diametrically opposed nibs or lugs 3l formed onthe free end of the stein or shank 25 to engage the flange 29, and inlthis manner the stem .or

shank 25 yis detachably fastened in. the sleeve 26. l.integral with orsecured to the sleeve 26 at its uppermost end is a plurality ofdiametrically opposed resilient limbs or arms 82, the same beingdisposed in downftvardly divergent relation to the sleeve 26 and areformed with free hook ends 33 which are adapted 'to :be driven into thesupport of the article of furniture when the holder is inserted'in thesocket therein, and in this manner the said holder is irrnly fastened inthe support so as to prevent it from dropping out should the article offurniture be lifted.

Inthe use voli the caster it lWill be clearly apparent that the flooring-or foundation, Whether it be polished or roughened, Will article' offurnitureis moved from 'one point -not become scratched or marred when'the f to another thereover. rlfhe resiliency.. of the n arms or' limbsvof the holders hereinbefore described enable the proper tting of thesame within the socket in the support for the article of furniture andalso frictionally hold it fast therein. lflhen the article of furnitureis moved the caster glides over the ooring or foundation as the stem orshank of the caster freely rotates within the holder when the article offurniture is being 'moved It will be apparent that the stem or shank byreason of the variance yof the length thereof with regard to the sleeveof the holdercan' automatically adjust itself longitudinally in thelatter when encountering anyY unevenness in the floor or foundation.

From the foregoing itis thought that the construction and manner ofuseof the device will be clearly understood, and there- Y fore a moreextended explanation has been omitted.

The combination with a caster shank, of a holder comprising a tubiformmember for receiving the shank and having a contracted inner end toforma bearing shoulder for the shank at one point thereof, an out-turnedannular liange formed at the outer end of the said member and forming abear-lng for the shank at another 'pointJ thereof, a resilient bonnetintegral with the member and forming a plurality of spaced outwardlydivergent resilient limbs for irictionally securing the holder in anarticle of furniture, and means at the free end of the limbs to engagewith the Flange on the member and also With the article oi furniture forreinforcing the a-nge and also for limiting the inward movement of theholder in the said furniture.. i

ln testimony whereof l affix my signature in presence ,of two witnesses.
